## Transcript

[0:46] SPEAKER_02: Welcome to Science Is Not Boring by kidopoly.com.
[0:50] SPEAKER_02: I'm Mira.
[0:51] SPEAKER_02: And I'm Finn.
[0:53] SPEAKER_02: Before we start today, we have a huge shout-out.
[0:56] SPEAKER_02: A big hello to Harper, who is seven, and her little brother Banks, who is four, all the way in Tennessee.
[1:03] SPEAKER_01: We hear you two listen to our show together in the car.
[1:06] SPEAKER_01: And you specifically asked us to talk all about sandstorms.
[1:11] SPEAKER_01: That is right.
[1:12] SPEAKER_02: Hold on to your hats, because this one is for you both.
[1:16] SPEAKER_01: I am already holding on to mine.
[1:18] SPEAKER_01: Sandstorms sound super intense.
[1:21] SPEAKER_02: Oh, they really are.
[1:22] SPEAKER_02: Imagine standing in the middle of a hot desert and you look up to see a solid wall of dust racing towards you.
[1:29] SPEAKER_01: Wait, how big of a wall are we talking about?
[1:33] SPEAKER_02: Try 5,000 feet tall.
[1:35] SPEAKER_02: That is almost a mile straight up into the sky.
[1:39] SPEAKER_01: No way! That is like stacking three and a half empire state buildings on top of each other.
[1:45] SPEAKER_02: Exactly! Today we are diving into how the desert literally takes flight, turning into a towering monster of sand.
[1:53] SPEAKER_01: Let's find out how they form.
[1:54] SPEAKER_01: And more importantly, how humans and animals survive inside one.
[1:59] SPEAKER_01: To understand a sandstorm, you actually have to look up at the clouds, not down at the sand.
[2:04] SPEAKER_01: Wait, really?
[2:06] SPEAKER_01: But the sand is on the ground.
[2:08] SPEAKER_02: True, but the most intense dust storms actually start with thunderstorms.
[2:14] SPEAKER_01: Oh, I know thunderstorms.
[2:15] SPEAKER_01: Lots of rain and lightning.
[2:17] SPEAKER_02: Right, but in super dry places like the Sahara Desert in Africa, or Arizona in the United States, something weird happens.
[2:27] SPEAKER_01: What happens?
[2:28] SPEAKER_01: Does the rain turn to mud?
[2:30] SPEAKER_02: Not quite.
[2:31] SPEAKER_02: The rain often evaporates before it even hits the ground, because the air is so incredibly hot.
[2:37] SPEAKER_01: Wow, the air just eats the rain.
[2:40] SPEAKER_02: Yes, and as that rain evaporates, it cools the air around it really fast.
[2:45] SPEAKER_01: Cold air is heavy, so it plummets toward the earth.
[2:49] SPEAKER_01: Like a giant invisible water balloon dropping from the sky.
[2:53] SPEAKER_02: That is a perfect way to picture it.
[2:55] SPEAKER_02: Scientists call this a downdraft.
[2:58] SPEAKER_02: This freezing cold air smashes into the ground at speeds of 50 to 80 miles per hour.
[3:04] SPEAKER_01: Whoa that is as fast as a car driving on the highway.
[3:08] SPEAKER_02: Exactly.
[3:09] SPEAKER_02: When that heavy air hits the dry desert floor, it splats outward in all directions.
[3:15] SPEAKER_01: And since the ground is covered in loose sand, it just acts like a giant broom.
[3:20] SPEAKER_02: You nailed it! It sweeps up all that loose silt, clay and sand, lifting it thousands of feet into the air.
[3:28] SPEAKER_02: Meteorologists call these massive dust walls a haboob.
[3:33] SPEAKER_01: Haha, a haboob?
[3:34] SPEAKER_01: That is a funny word.
[3:36] SPEAKER_02: It comes from the Arabic word hab, which means wind or blow.
[3:40] SPEAKER_02: And they are huge.
[3:42] SPEAKER_02: A haboob can be up to 62 miles wide.
[3:46] SPEAKER_01: 62 miles?
[3:48] SPEAKER_01: That is wide enough to swallow entire cities in seconds.
[3:52] SPEAKER_02: People who have seen a haboob say it looks like a giant land-based tsunami.
[3:57] SPEAKER_02: The sky turns a rusty orange and then completely black.
[4:02] SPEAKER_01: Completely black?
[4:04] SPEAKER_01: Like nighttime in the middle of the day.
[4:07] SPEAKER_01: Yes.
[4:08] SPEAKER_02: In fact, one of the most famous dust storms in history happened on April 14th, 1935, during a time called the Dust Bowl in America.
[4:18] SPEAKER_02: Was that the one they called Black Sunday?
[4:21] SPEAKER_02: Exactly.
[4:23] SPEAKER_02: A mountain of black dust swept across Oklahoma and Texas.
[4:28] SPEAKER_02: The winds hit 60 miles per hour.
[4:31] SPEAKER_01: That must have been so terrifying for the people living there.
[4:34] SPEAKER_02: It was.
[4:35] SPEAKER_02: The blackness was so complete that people reported they could not even see their own hand if they held it right in front of their face.
[4:43] SPEAKER_01: I would be so panicked.
[4:45] SPEAKER_01: What do you even do if you get caught in something like that today?
[4:49] SPEAKER_02: Well, the great news is, today we have advanced weather radars and satellites that track Kaboob's forming.
[4:57] SPEAKER_01: Oh, so scientists can warn people before the storm arrives?
[5:01] SPEAKER_02: Exactly.
[5:02] SPEAKER_02: Meteorologists send out emergency alerts to phones and radios.
[5:07] SPEAKER_02: The main rule for drivers is to pull safely off the road, turn off all their lights and wait.
[5:13] SPEAKER_02: Why turn the lights off?
[5:15] SPEAKER_02: Wouldn't you want to be seen?
[5:17] SPEAKER_02: If other drivers see your tail lights in the thick dust, they might think you are moving on the road and accidentally follow you right off the shoulder.
[5:25] SPEAKER_01: Wow, that is such a clever safety trick.
[5:28] SPEAKER_01: I never would have thought of that.
[5:30] SPEAKER_02: By pulling over and hunkering down inside, humans can stay perfectly safe while the desert flies past outside.
[5:38] SPEAKER_01: But wait a minute! Humans have cars and houses to hide in.
[5:43] SPEAKER_01: What about the animals out in the desert?
[5:45] SPEAKER_01: That is one of the coolest parts of science.
[5:48] SPEAKER_02: Animals have evolved incredible ways to survive sunstorms.
[5:52] SPEAKER_01: Okay, tell me about camels.
[5:54] SPEAKER_01: They live in the Sahara and the Gobi Deserts, right?
[5:57] SPEAKER_02: They sure do.
[5:58] SPEAKER_02: And the Bactrian camels in the Gobi Desert face extreme weather.
[6:03] SPEAKER_02: They can survive freezing winters down to negative 22 degrees Fahrenheit, and scorching summers up to 122 degrees.
[6:13] SPEAKER_01: That is wild! But a sandstorm must be a camel's worst nightmare, because sand is super scratchy.
[6:20] SPEAKER_01: How do they protect their eyes without goggles?
[6:23] SPEAKER_02: Actually, they basically have built-in desert goggles.
[6:27] SPEAKER_02: Camels have three eyelids.
[6:30] SPEAKER_01: Three eyelids?
[6:31] SPEAKER_01: Humans only have two.
[6:33] SPEAKER_02: Right, but a camel's third eyelid sweeps across the eye from side to side, like a windshield wiper on a car.
[6:40] SPEAKER_01: That is so weird.
[6:42] SPEAKER_01: But doesn't closing their eyes mean they can't see where they are going?
[6:45] SPEAKER_01: Here is the mind-blowing part.
[6:47] SPEAKER_02: That third eyelid is translucent, meaning it is thin and clear enough to see through.
[6:53] SPEAKER_01: No way.
[6:54] SPEAKER_01: So they just close their clear eyelid and keep walking while the sand bounces right off.
[6:58] SPEAKER_02: Exactly.
[7:00] SPEAKER_02: Plus, they have two rows of super thick, long eyelashes that lock together like combs to block the dust.
[7:07] SPEAKER_01: That is a serious superpower.
[7:09] SPEAKER_01: But what about breathing?
[7:10] SPEAKER_01: Wouldn't their noses get full of sand?
[7:13] SPEAKER_02: Mother Nature thought of that too.
[7:15] SPEAKER_02: Camels have special muscles in their noses that allow them to squeeze their nostrils completely shut.
[7:21] unknown: Ha!
[7:22] SPEAKER_01: They can pinch their own nose closed without using hands.
[7:25] SPEAKER_01: I wish I could do that when we drive past a stinky garbage truck.
[7:29] SPEAKER_02: It is an amazing trick.
[7:31] SPEAKER_02: Even their ears are lined with thick hair on the inside and outside to keep the dirt out.
[7:36] SPEAKER_01: So a sandstorm is just another Tuesday for a camel.
[7:39] SPEAKER_01: They just zip up their nose, drop their see-through eyelids, and wait it out.
[7:44] SPEAKER_02: So, the sand blows around the desert and then it settles back down.
[7:48] SPEAKER_02: End of story, right?
[7:50] SPEAKER_01: I feel like you're about to tell me the answer is no.
[7:54] SPEAKER_02: Not even close.
[7:55] SPEAKER_02: Dust storms have a massive impact on the entire planet.
[7:59] SPEAKER_02: The wind can lift the finest, lightest dust high into the atmosphere, where jet streams carry it across the world.
[8:07] SPEAKER_01: Are you saying Sahara Desert Sand travels across the ocean?
[8:11] SPEAKER_02: Yes.
[8:12] SPEAKER_02: NASA uses a satellite called Calypso to measure it.
[8:16] SPEAKER_02: Every single year, over 132 million tonnes of Saharan dust blows all the way across the Atlantic Ocean.
[8:25] SPEAKER_01: Over 132 million tonnes?
[8:29] SPEAKER_01: That sounds like the weight of 22 million elephants.
[8:32] SPEAKER_01: It is an unbelievable amount.
[8:35] SPEAKER_02: And guess where exactly 27.7 million tonnes of that African dust lands?
[8:41] SPEAKER_01: I have no idea.
[8:43] SPEAKER_01: Europe?
[8:44] SPEAKER_01: Antarctica?
[8:45] SPEAKER_01: It lands in South America, right on top of the Amazon rainforest.
[8:50] SPEAKER_01: The biggest desert in the world sends its dust to the biggest rainforest in the world.
[8:55] SPEAKER_01: Why?
[8:55] SPEAKER_01: Because the Amazon needs it.
[8:58] SPEAKER_02: Rainforest soil actually lacks certain nutrients because the heavy rains constantly wash them away.
[9:04] SPEAKER_01: Oh, so the plants get hungry.
[9:06] SPEAKER_02: Exactly.
[9:07] SPEAKER_02: But that Saharan dust is packed with a mineral called phosphorus.
[9:11] SPEAKER_01: So the dust acts like a giant cloud of fertiliser falling from the sky.
[9:16] SPEAKER_02: You got it! Without the massive sandstorms thousands of miles away in Africa, the lush green Amazon rainforest would not have enough food to survive.
[9:26] SPEAKER_01: That is the most incredible thing I have ever heard.
[9:29] SPEAKER_01: Everything on Earth is truly connected.
[9:32] SPEAKER_02: It really is.
[9:33] SPEAKER_02: A violent storm in a dry sandy wasteland brings life to a jungle on the exact opposite side of the planet.
[9:40] SPEAKER_02: Speaking of looking closely at how everything connects, let's see how closely you were listening.
[9:47] SPEAKER_02: It is quiz time!
[9:49] SPEAKER_01: I am ready.
[9:50] SPEAKER_01: Hit me with your best questions.
[9:53] SPEAKER_02: First question, what is the scientific name for a massive dust storm that comes from the Arabic word for wind?
[10:04] SPEAKER_02: Next one.
[10:06] SPEAKER_02: How many eyelids does a camel have to protect its eyes from the sand?
[10:14] SPEAKER_02: Question three.
[10:15] SPEAKER_02: How tall can a haboob grow in feet?
[10:22] SPEAKER_02: Here's number four.
[10:24] SPEAKER_02: What year did the famous Black Sunday dust storm happen in America?
[10:32] SPEAKER_02: Last question.
[10:34] SPEAKER_02: The Sahara Desert sends millions of tons of dust across the ocean to feed which famous rainforests?
[10:44] SPEAKER_02: Great job! Let's see how you did.
[10:47] SPEAKER_02: The first answer is it is called a haboob.
[10:51] SPEAKER_02: For question two, a camel has three eyelids, including that awesome see-through one.
[10:58] SPEAKER_02: Number three, the answer is a haboob can grow up to 5,000 feet tall.
[11:05] SPEAKER_02: Question 4.
[11:06] SPEAKER_02: Black Sunday took place in the year 1935 during the Dust Bowl.
[11:12] SPEAKER_02: And the final answer is, the dust fertilises the Amazon rainforest.
[11:17] SPEAKER_01: I definitely would not want to get caught in a 5,000-foot wall of dust.
[11:22] SPEAKER_01: But I have a whole new respect for her boobs.
[11:25] SPEAKER_02: Right?
[11:26] SPEAKER_02: And I will never look at a camel the same way again.
[11:30] SPEAKER_02: Nature is just full of brilliant surprises.
